Phys.org / How fishing may be changing one fish species at the molecular level
The pearly razorfish (Xyrichtys novacula) is a small marine animal that lives in sandy coastal waters and feeds on creatures like shrimp. Known locally in Spain's Balearic Islands as raors, it is a popular dish in many homes ...
Phys.org / Unwritten social rules, not government oversight, help keep forest land sustainable
Swidden agriculture—often called "slash-and-burn"—has been practiced on every inhabited continent throughout human history, and for decades it has been blamed for the destruction of the world's rainforests. However, a new ...
Phys.org / Why evolution never produced mammal teeth that slice and crush equally well
Evolution is all about trade-offs. Traits that may be beneficial in one situation may backfire in another. Over millions of years, species can become specialized for one way of living rather than being equally good at everything. ...
Phys.org / Plumage reflectance framework offers new insight into how birds evolved heat-controlling feathers
Birds can inhabit various environments with different climates and temperatures, ranging from cold polar regions to scorching hot deserts. To survive and thrive in these very different environments, they need to effectively ...
Medical Xpress / Kids do feel the cold, so why won't they wear a sweater?
It happens just when you need to leave. Bags are packed. Shoes are on. Then your child decides a sweater is impossible. You say, "Put your sweater on." They say, "I'm not cold." Do kids really not feel the cold like adults ...
Medical Xpress / Time-restricted eating may help retain cognitive function in older adults
Results from a small clinical trial suggest it may be possible to reduce the risk of dementia by eating during fewer hours of the day. The pilot study, which involved a weight-loss program for older women with overweight ...
Phys.org / Syria's ancient sites face widespread looting and systematic bulldozing, satellite images reveal
Dozens of archaeological sites were destroyed by looting during Syria's civil war, which began in 2011 and lasted until 2024. Because the last comprehensive analysis was published in 2017, the extent of more recent damage ...
Phys.org / When a teenager makes the 'stupid choice,' their brain is working exactly as designed
When an adult refuses to let an injustice pass—stands up to a bully or asserts their rights—we call it principle. When a 15-year-old retaliates to an insult thrown in a school corridor, risking detention, we call it a failure ...
Phys.org / Quantum internet leaves the lab with first real-world entanglement over busy telecom fiber
Quantum information is notoriously fragile. Internet traffic is anything but. Yet Northwestern University scientists have demonstrated they can peacefully coexist inside the same fiber-optic cable.
Phys.org / The hunt for a natural molecule that can release cellular energy
All cells in the human body—and the motions they enable, from our beating hearts to our wiggling toes—use energy generated by a molecule called ATP. Its energy is thought to be released to fuel cellular processes in only ...
Dialog / 'Pro version' of cisplatin keeps its cancer-killing power while reducing side effects
Cisplatin is one of the most successful cancer medicines ever developed. Doctors use it to treat many cancers, including lung, ovarian, breast, testicular and head and neck cancers. However, cisplatin has a serious problem. ...
Phys.org / Small tropical islands face dangerous humid heat by end of the century
Millions of people living on tropical islands could face a future of increasingly dangerous heat as climate change drives longer and more intense periods of humid conditions. While rising temperatures are often discussed ...
